SPECIFICATION forming part of Letters Patent No. 656,82 5, dated August 28, 1900. Applicants summum 29, 1900. sans No. 3,144. (No man.)

.To all whom it may concern.:

Be it known'that I, GEORGE'PL'MOINTYRE, a citizen 4of the "United States, residing at Chicago, in the county of Cook-and State of of the package after the inspection.

More particularly my present invention relates to an improvement upon the construction pf mailing-tubes for which Letters Patent of the United States No. 524,860 were granted to me August 2l, 1894.

The mailing-tube of my afpresaid patent, while adapted to aord a receptacle for mailable articles generally of the character suitable for transmission in tubes, is not espev cially designed for holding; `itguids or liquids in fangible receptacles for transmission by mai My object novir is to providea constructionof mailing-tube especially adapted for holding liquids for mailing and which, While possessing the attributes' hereinbefore referred to of permitting ready access to its contents and ready reelosure of the package after .inspection of its contents, shall, besides being Waterproof and capable of close sealing against leakage, be provided with acover and fastening means therefor soconstructed as to cause the cover to brace the tube in an outward direction against crushingstrain exerted against it and to cause the coverffasten# ing means on the tube to cooperate with the cover to resist transverse elongation of the tube at ifs covered mouth portion, which .4 would obviously then open it and aord a leak in the receptacle even thouglrjthe cover` remain 1n place under the strain referred to.

In `the accompanying drawings, Figure 1 is .aview infvertical sectionaltlefltion of my improved mailing-tube, showingl allits `parts but the cover Vand washer; Fig. 2,1a similar but broken View of the .samegshowing the cover fastened in place; Fig. 3, a crosseseci best formed of Wood saturated tional view of the cover; Fig. 1t, a similar view of a Washer detail; Fig. y5, a similar view of a modified form' of the Washer, and Fig. 6 a perspective View of a clip detail.

` A is the tube, comprising two tubular vsec-` tions A'- and A2, fastened together, as by cementing one Within the other, the outer one being the longer of the two to afford the internal end shoulders r and r', which form seats, respectively, for the head p and coverB.Y

While I do not limit my improvement to any particular` material out of which to form the tube, -that selected must of course be suitable for the purpose of the tube, and because it should for economical reasons be as light as is consistent with the requirements of `strength'and durability I prefer to select as the material ordinary pasteboard.

In forming the tubular portion of my im` proved device, which may be done by inserting the one tubular section into the other with l contain an' opening o, through which to ad' mit the cement provided between the tubef sections, so that when the cement becomes hard it affords a species of key in the clipopening.

The end of the tube A at the shoulder .r is

permanently closed by the hemamdp, which is in shglag aldvhichts against and is cenc'fted to the shoulder r', the head being, by preference, further secured in position by means of a covering m of cloth cemented about `the inner tube-section A', adjacent to the shoulder fr', and to hide vthis cloth covering I prefer to cement against its outer. surface a thin disk of paper or pasteboard Z. i

When the tube A is formed ofpasteboard, to render it waterproof I coat it internally Witharaffin 7 r some other suitable Waterproong material.

by preference,

The cover B should be forniedif-y metal in the generally concavooonvcx shape illustrated, and about its edge it is provided with an upwardly-flaring iiange 1I, which should,

be slightly curved in crossseotion, as represented. Against the shoulder r Iapply a Washer 72, which is best formed of rubber, and it may be beveled, as shown at from its upper outer edge to its lower inner edge to afford a closeiitting seat for the cover, conforming moreor less accurately to the cross-sectional approxir'nate--v Vshape of the'iianged edge of the cover. The rubber Washer 7L may also be tubular and r nid in cross-section, as shownrin Fig. 5. With the cover in its seat the clips C are bent over its flange t' and secure it in place in a man? ner to permit it to be readily removed on bending back the clips.

As Will be seen, any pressure or Weight that .isbrought to bear against 'the side of myimproved tube A, with the @over fastened in the bottle; vescaped from the tube.

What I claim as new, and HbyfLettersPatent, is- 1 1.A mailing-tube comprising a tubular `lo`oily-having a permanently-fastenedeover at oneendgand an internal shoulder and flexible place, if sufficient to indent or-c not necessarily bend the mouth pY 'tion even if the force were great enough to bend the hoover, since in order so tobeud it the tube.

about it would also havet'ol bend, and its tenden'oyto do so is resisted by the outward pulll Which then the o li ps would be caused toexert against the cover at its flange'.v In faot, I have eauseda heavy load to be driven over my improved mailing-tube between its ends and While containing a. bottle of liquid, and the only effect-of crushing the tubenas to break but none of the desi re to secure metal clipsfat itsl opposite end, in oombinantionWith'a Washerseating against said shoulderand-a anged cover seating in said Washer against the shoulder in positionfto be engaged h it will` e enanas at its flange by said clips, substantially as and for the purpose set forth.

2. A mailing-tube comprising a waterproof tubular body having a permanentlyefastened sx cover at one end and an internal shoulder 5o and flexible metal clips at its opposite end, in combination with a washer sealing against said shoulder and a circular outvvardly-con- Vex @overl-E having the circumferential fiange e' and seating against said Washer in position 55 to be engaged at its iiange by said clips, substantially as and for the purpose set forth.

3. A mailing-tube comprising a Waterproof tubularbody formed ofthe external and internal tube-sections A and A2 fastened together 6o extend beyond said shoulder, in combination' 65 with a flanged cover B seated against said shoulder in position to be engaged by said clips, substantially as and for the purpose set forth.

4. A mailing-tube comprising, in combination, a Waterproof tubular body A formed of the external and internaltube-sectionsA and A2 fastened together and forming the inter- .nal shoulders r and r at its opposite ends, a head p permanently seated `against the shoul- 7 5 der r and havin g a cover m extending overit,

clips C having openings o at which they are keyed between said. sections at the end of the tube adjacent to the'should'er r to extend beyond it, a Washer h seated againstthe shoul- 8o der r and a cover B provided with a circumferential flange e' and seating against said Washer in position to be engaged clips, substantially as and for set forth.
